更改 iPython 笔记本服务器 / Jupyter 的默认端口

我想在防火墙后面的机器上运行ipython笔记本/jupyter服务器。唯一开放的端口是80号端口。所以我想知道如何将默认端口从8890更改为80？

我已经运行了以下命令ipython profile create来创建一个配置文件。

然后编辑了ipython_notebook_config.py文件，并将其编辑为包含以下内容：

c = get_config()
c.NotebookApp.port = 80

当我尝试运行Python笔记本时，出现以下错误:

ERROR: the notebook server could not be started because no available port could be found.

然而，似乎没有其他东西在使用端口80。Apache不会在启动时启动并且已禁用。我甚至使用netstat查看了每个端口的使用情况。

为了临时更改端口号，我们可以在终端启动Jupyter笔记本服务器时，通过执行以下命令来指定不同的端口号。

jupyter notebook --port 9999

我不同意@Billa的观点。我认为这是最好的答案。它简单易懂且有效。 - Jinhua Wang

在Jupyter中，我们可以通过两种方式在不同的端口上启动笔记本。

临时端口 - 通过在命令参数中指定端口号，我们可以在该端口上运行Jupyter。但是，每当我们需要在不同端口上运行Jupyter时，都必须在命令参数中指定端口号。

jupyter notebook --port 9999

永久端口配置 - 通过更改配置，我们可以在机器上永久运行不同端口的Jupyter。请按照以下步骤操作。
- 使用nano打开配置文件
nano ~/.jupyter/jupyter_notebook_config.py
- 通过更改以下配置的值来更改端口
c.NotebookApp.port = 9999
- 启动笔记本
jupyter notebook

Bingo!!!

已经有一个服务在80端口上监听了，你不能将两个服务器绑定到同一个端口。使用一个代理监听80端口，并将其重定向到其他基于URL或地址的服务器和IPython，不要使用80端口，如果你运行的是公共服务器，则应该使用443端口进行TLS安全传输。

请注意，对于任何低端口号，您可能需要提高进程特权以root权限运行，可能需要使用sudo命令。

据我所知，没有其他进程在使用端口80。不幸的是，我无法决定组织外可访问的端口号。说实话，实际数字是任意的，但设置代理真的是最好的方法吗？ - jonhurlock

2

你正在以root用户身份运行吗？如果没有足够的权限，你将无法绑定到较低的端口。 - Matt

这是因为它是一个较低的端口，所以我必须使用sudo命令来启动服务器sudo ipython notebook --profile=nbserver / sudo ipython notebook --port 80。祝好 @matt - jonhurlock

这是正确的答案。端口80是特殊的，应用程序让其难以访问有很好的理由（例如，这是一个安全问题）。请不要以Sudo用户身份运行公开可访问的东西。设置Apache（或nginx，或其他），将代理设置为转发到端口8888。完成并且安全。如果您在该服务器上添加其他应用程序，则Apache可以处理它们所有。 - hendrixski

在某些情况下，端口是通过环境变量（如在Docker镜像中）自动选择的。您可以更新此变量。我猜这应该适用于所有情况：

# Export
export JUPYTER_PORT=80

# Start the notebook
jupyter notebook

仅供参考，运行在Docker容器中并更改配置以使用端口80：

c.NotebookApp.port = 80

依次引起以下错误：
